BODROV GRIP BRAKE Russian patent published in 2018 - IPC F16D65/95 B61H5/00 F16D55/224 

FIELD: transportation.

SUBSTANCE: invention relates to the braking equipment of railway vehicles. Grip brake includes a horizontal frame which is rigidly fixed to the side frames of the bogie and on the transverse beam of which two pairs of holders and the mechanism of counter movement of the holders are supported with the possibility of transverse reciprocal movement. In the transverse beams, the holders of each pair are located on both sides of the wheels and are connected to horizontal brake shoes. Mechanism of counter movement of holders is made in the form of at least one, but preferably four or six, depending on the number of wheels in the bogie, horizontal L- or T-shaped two-arm levers. Long shoulders of two-arm levers are pivotally connected to the traction of the brake system of the car, and short shoulders – with holders. Holders are supported by the transverse beams of the horizontal frame without the possibility of longitudinal movement along the trolley.

EFFECT: improved reliability and simplification of the bogie brake design is achieved.
